You can pick the complete source from examples directory/LwIP project. It compiles just like any other project. You can access the makefiles and sources right away. No dependancy on any hidden stuff there. Same with mbedTLS (available as a complete different ZIP). Anyway, we are trying to fix things...

Yes, almost all ESP-12Fs bought here work with QIO. We have had some non-AI-Thinker modules with a pacman on the shielding can. Those are the onces that do not work with QIO even though they are specified as QIO. I did not open the can up and check the insides of that. But they are not AI-Thinker br...

Yes, that is all correct. Note that the Getting Started Guide just tells you about the default LD file settings. If you want you can modify the addresses and get the code where you want it to be. Will take a little trial-and-error though.

The sources for LwIP and mbedTLS have always been open and public. You may try to modify the code yourself if you can and share the resultant code if it works. It is really difficult to debug issues on our end because often the connection/disconnection callbacks depend on the routers and when the ev...

AT+UART_CUR=115200,8,1,0,0 This works fine, all of your commands work fine. But the firmware you are using is not an official Espressif release I think. I don't recognize the firmware version number. The manual you sent the link to (PDF file) is WAYYY too old. There have been hundreds of revisions s...

It might be a bug with your STM32 code to pass data through.The best way to debug this is to simple hook up logic analyzer between PC-STM32 and STM32-ESP.When you see that the streams are exactly similar with slight time shifting, you know that your STM32 is behaving well with passing data on.

The ESP8266 SPI slave uses the SDIO slave, which is unfortunately sharing pins with the SPI flash chip. So to get the AT firmware with passthrough up and running, what you need to do is: 1. Have ESP8266 with flash on HSPI interface (as in ESP-WROOM-S2, not in regular ESP modules that runs user code)...
